My wife and I went with a couple of friends (all >40) with varying levels of fitness (and shapes, and sizes). We all had a blast. It is a very well organized ropes course. It is very safe - you are always locked-in to a cable at one or more points at all times. The courses have varying degrees of difficulty that could keep you engaged for several hours over more than one day. We were there for ~2 - 3 hours, which was perfect for us. I look forward to returning with my son.
